CONVEYER AND GUIDE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 699,133, dated May 6, 1902. Application filed October 4,1901. fierial No. 77,556. (No model.)

To all whom it may concern: 1

Be itknown that LTHOMAS V. ALLIs,a citizen ofthe United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Conveyers and Guides forRolling-Mills, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to rolling-mills, and

is designed to guide and convey metal plates or packs from one set of reducing-rolls to another set of reducing-rolls. 1 It consistsof two endless chains cooperat; ing and traveling on a horizontal plane and at a uniform linear-speed, the form of the.

,links being adapted to engage and hold the metal plates on packs at their opposite ends and to present theadvancing edge of the plates ,or packs sq arely to the bite of the succeedingreducing-rolls.

To enable others to understand my invention reference is had to the accompanying drawings, in which- Figure 1 represents a plan view including the lower rolls'of two sets of reducing rolls with their housings removed, a chain conveyer with sprocket-wheels for imparting motion to the chains, and chain-tighteners and adjusting devices.

tional view of the chain conveyer through line a of Fig. 1, a sectional view of the floor on which rest the standards for supporting the chains, vertical shafts for driving the chains, and mechanism below the floor for driving the shafts, with broken view of an overhead beam in which the upper ends of said shafts are journaled and to the under side of which one of the tightener-brackets' is secured and opposite a broken view of one of the tighteners. Fig. 3 is a broken side elevation of one section of the chain conveyor looking in the direction of arrow (2, Fig. 1, showing a broken sectional view of the floor and a sectional view of the overhead supportingbeam and one of the adjustingscrews, and an end elevation of the reducing-rolls. Fig. 4: is a side elevation of oneof the end sprocket-wheels, its frame, and a broken view of its supporting-standard. Fig. 5 is an enlarged plan view of a section or part Fig. 2 is an end view showing a pair of reducing rolls 1, a sec-r on the standards 22, 23, 24, and 25. frames carry the rotating sprocket-wheels 26,

packs of metal plates, and Fig. 6 is a broken sideelevation of the same looking in the direction indicated by the arrow 0 in Fig. 5. Fig. 7 is a plan view of adevice for automatically adjusting the distance between the conveyer chains, the view including the sprocket-wheel frames and their supportingstandards. Fig. 8 is a side elevation of one 0fthe sprocket-wheel frames, including a broken view of its-standard and similar view of one of the arms ofrthe paralleldevice for automatically operating the frames.

The chain conveyer shown in the enlarged views, Figs. 5 and 6, is composed of the broad links 1 and 2, and the narrow interposed links 3, pivotally connected to said broad links by the pins 4. The end edges of the metal packs broad links 1 and 2 and are supported on the links 2, while the vertical sides ofthe narrow links 3 form a. supporting-wall for the ends of the packs sufficient to guide them squarely into the bite" ofthe reducing-rolls.

Referring to Fig. 1, the two sections 6 and 7'of the endless-chain conveyer'are shown located between the two sets of reducing-rolls 8 and 9. 10 and 11 (see also Figs. 2 and 3) are vertical shafts supported in-the bearings 12'and 13 in the floor'lt and extend below the same and are driven by the shaft 17. 15 and 16 are'sprocket-wheels mounted on said shafts to engage with and drive the chain conveyer; In the respective figures, 18, 19, 20, and 21 are short forked frames pivotally supported 27, 28, and 29, around which the conveyerchainspass. By adjusting said sprocketwheels the'conveyer-chains are adjusted to the Width of the plates or packs conveyed.

For this purpose the adjusting-screws 30 and.

3.1 are used. These screws carry right and left hand threads and are mounted in swiveled lugs depending from the under side of each of the forked frames. One of these lugs, 32, is shown at Figs. 3 and 4. By means of these adjusting-screws. the conveyor-chains are set the proper distance apart to accommodate the width of the plates or packs being rolled. I

33 and 34;, Figs. 1 and 2, are tightener-rolls These through.

pivotally supported in the sliding frames 35 and 36, which frames are operatively mounted in the hangers 37 and 38. These hangers are supported on the under side of the beam 39, which beam also supports the upper end of the shafts 10 and 11. 40 and 41 are the adjusting-screws for said tightener-rolls.

At Figs. 7 and 8 are shown devices for automatically adjusting the distance between the conveyer-chains, which eifects a parallel movement of the respective ends of the conveyer by means of the arms 42 and 43, pivoted at their center by the pin 44. 45 is an adjusting-screw on the arm 43, adapted to engage the stop 46 on the arm 42 at one side of the center, while the opposite side the arm 42 carries the ad j listing-screw 47 to engage the stop 48 on the arm 43. 49 and 50 are retractile springs adapted to preserve the engagement of these adj listing-screws with their stops. 51, 52, 53, and 54 are ears projecting from the forked frames 18, 19, 20, and 21, carrying the studs 55, 56, 57, and 58, to which studs the ends of the parallel arms are pivoted. This arrangement is essential where there is any variation in the width of the packs, which may occur from irregular shearing. With this arrangement when a wide pack passes the rolls it will force apart the conveyerchains against the tension of the springs 49 and 50, which springs, as before mentioned, will always bring said chains back to their normal position after the wide pack has passed Being a parallel movement, both ends of the conveyer operate in unison.

While I show certain mechanical means for supporting, driving, adjusting, and tightening my improved chain conveyer, I do not wish to be confined to any particular means for accomplishing these purposes, as they may be varied to suit the requirements of each particular case. The gist of my invention consists in constructing certain links of the chain conveyer wider than others and to operate the chain on a horizontal plane,whereby the broad links form. a groove in which the ends of the plates or packs are confined in transit, while the narrower links form a guide for their ends to abut against, and, further, to arrange the chain feed into two endless-chain systems whose inner feeding-lines move in the same direction and in unison with each other and at the same linear speed,

by which I accomplish the very important and indispensable requirement of conduct- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A conveyer for metal plates or packs consisting of two endless chains cooperating on a horizontal plane and composed of wide and narrow links, the wide links adapted to support the ends of the plates or packs, and the narrowlinks adapted to act as side guides, for the purpose set forth.

2. A metal-conveyer, consisting of two endless chains operating in unison on a horizontal plane and at the same linear speed and composed of wide and narrow links adapted to both support and guide the metal in trausit, for the purpose set forth.

3. A conveyer for metal plates or packs, consisting of two series or systems of endless chains arranged parallel with each other and operated on a horizontal plane and at the same linear speed so as to squarely guide the metal in transit, for the purpose set forth.

4. A conveyer for metal plates or packs, consisting of two series or systems of endless chains arranged parallel with each other on a horizontal plane and to cooperate at the same linear speed, the chains adapted to both support and squarely guide the metal in transit, combined with means whereby the path of feedway of the metal may be adjusted for different widths of plates or packs, for the purpose set forth. 7

5. A conveyer for metal plates or packs, consisting of a double series of endless chains arranged parallel with each other and adapted to cooperate at the same linear speed, the chains adapted to both support and squarely guide the metal in transit, combined with means for adjusting the width of the feedway and means for propelling and tightening said chains, substantially as described, for the purpose set forth.

6. A conveyer for metal plates or packs, consisting of a double series of endless chains arranged parallel witheach other and adapted to cooperate at the same linear speed, the chains adapted to both support and squarely guide the metal in transit, combined with means for regulating the width of said conveyer, and means for automatically adjusting and maintaining a parallel movement with varying widths of plates or packs, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
